(SLIDE SHOW) It's hard to describe this self-titled World Famous Ricky Powell Slide Show—it's part photography slide show, part guided tour through the wild-styled streets of NYC circa 1985. Using only a beat-up Minolta, the wisecracking "fourth Beastie Boy" captured amazing portraits of some of old-school New York's finest—characters like Run-D.M.C., Fab 5 Freddy, Keith Haring, and Jean-Michel Basquiat. There's photography and graffiti-art collaborations, but most importantly there's the man himself telling you, first-person, the whole crazy story.
